WASHINGJVIACHINE.

Specification of Letters Patent.

Application led October 8, 1910. Serial No. 586,111.

invented a new and useful VVashingdVIa-l chine, of which the followingis a speciiication.

It is the object of this invention to provide a washing machine, havinga tub and a cooperating rubbing surface of novel form.

1With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and'in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofthe claim without departing from the spirit of the invention.

In the drawings, Figure 1 shows the invent-ion in side elevation, partsbeing broken away; Fig. 2 is a horizontal section on the line 2 2 ofFig. 1; Fig. 3 is a fragmental vertical section, the same being in thena,- ture of a diagrammatic view, showing the means whereby the spiralsprings which constitute the rubbing surface of the tub, are held inplace upon the tub; and, Fig. 4 is a fragmental plan showing the mannerin which the springs may be held in place upon the tub.

In the drawings, the tub is denoted generally by the numeral 1. This tub1 may be of any desired form. In the present instance it is shown asconsisting of a plurality of staves 2, certain of which are prolonged,to form the legs 3 of the tub. The staves 2 may be held in place bymeans of bands 4. Fixed to the tub 1, is a top 5, having an openingwhich is closed by a lid 6, hinged at 7 to the. top 5. The top 5 of thetub carries a sto-p bracket 8, adapted to limit the rearward tilting ofthe lid 6. The top 5 is provided with the usual drainboard 9, positionedadjacent o-ne edge of the opening in which t-he lid 6 fits, t-he detaillast referred to being common, and requiring butI limited delineationand description.

The lid 6 is provided with a bearing 11, in which a shaft 10 isjournaledfor rotation, the shaft 10 having a crank portion 12, providedwith a suitable operating handle 14. The beater consists of a head 15,se-

cured in any desired manner to the inner end of the shaft 10, and arms16 carried by 'the head, the arms 16 being preferably,

although notA necessarily, of the looped,

lopen, .form clearly seen in Fig. 1. The bot- -tom 17 of the tub iscovered by a spiral spring, 18 disposed in helical form, as denoted bythe numeral 19 in Fig., 2. This spring, preferably, although notnecessarily, is carried in a single length upon the side walls of thetub, and continued upwardly along the side walls, in superposed coils asshown at 21. A bead 20 is located in the angle defined by the staves 2and the bottom 17. This -bead 20 overhangs the outer coils of thatportion of the spring which is disposed upon the bottom 17 of the tub.The spiral spring 18 is carried between the bead 2O and the stave 2, asdenoted by the numeral 23 in Fig. 3, and thence is carried upwardly uponthe side walls of the tub. The tub 1 is polygonal in form, andpreferably octagonal. In the angles, dened by the staves 2, uprightposts 22 are located, these posts 22 being extended downwardly intoclose relation with the bead 20. The superposed coils 21 vof the spiralspring, by which the side walls of the tub'are lined, are engagedbetween these posts 22 and the staves 2 as seen clearly in Figs. 2 and3.

The spiral springs which are located uponthe bottom and upon t-he sidewalls of the tub furnish an effective rubbing surface.

wWhen the beater 15-16 is rotated within the tub 1, the clothes will berubbed upon the portion 18 of the spring .which is located upon thebottom 17, and upon the coils 21 which are positionedupon the side wallsof the tub. Owing to the polygonal outline of the tub 1, the eiiiciencyof the superposed coils 21 will be increased, the clothes being forcedinto the angles between the staves 2, and swept out of these angles, asthe beater rotates.

The spiral spring may be secured to the staves 2 and to the bottom 17 inany desired manner. For instance, as shown in Fig. 4, the spring may bestapled in place, as shown at 24. In order that Fig. 2 of the drawingsmay not be confused, no specific means for securing the springs inplace, is shown in the said figure.

The ent-ire inner surface of the tub presents a rubbing surface ofunusual eificiency, the springs, however, yielding sufficiently, sothatI the garments, although re- Patented Apr. 15, 1913.

ceving` a thorough rubbing, will not be likely to be torn in the rubbingoperation.

Having thus described the invention what is claimed is A Washing machinecomprising a tub having its bottom covered by a spiral spring disposedin helical form, the side .Walls of the tub being covered by a spiralspring disposed thereagainst in a plurality of superposed coils, thecoils of the respective springs being in close and intimate Contact topresent continuous rubbing surfaces; and. :t beater jolunaled forrotation Within the tub.

In testimony that We claim the foregoing as our own, We have heretoailixed our sig- 1.3 natures in the presence of two Witnesses.
